AxLE-LUBRIOATOR.

SPECIFICATION forming part of Letters Patent No. 249,194, dated November8, 1881.

Application filed August 18, 1881. (No model.)

To all whom it may concern:

`Be it known that we, MATTHEW R. MARKS and ALFRED IVERSON, of Orlando,in the county of Orange and State of Florida, have invented certain newand useful Improvements in Axle-Lubricators; and we do hereby declarethat the following is a full, clear, and exact description of theinvention, which will enable others skilledin the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, which forrn a part of this specification.

Figure l is a vertical sectional view of a hub to which ourinvention hasbeen applied. Fig. 2 is a view inl perspective of our improvedaxle-lubricator detached; and Fig. 3 is a horizontal sectional view.

Corresponding parts in the several gnres are denoted by like letters ofreference.

This invention relates to axle-lubricators, and is an improvement on thedevice patented to ourselves,No. 241,500.

Our present invention consists in a simpler, less expensive, and moresatisfactorily operating combination, construction, and arrangement ofparts, as will be hereinafter fully described, and particularly pointedout in the claim.

In the drawings `hereto annexed, A repre-` sents the hub, and B thespindle, which, as well as the hub, may be of any suitable wellknownconstruction.

G is the lubricator, which consists of a tube, D, adjustable in asuitable perforation in the hub, where it is held by, means of screws E,inserted through a flange, F, at its upper end, said iiange beingcurved, as shown, so as to conform to the contour ofthe hub. I The tubeD is provided with a transverse pin, G, above which is located a coiledspring, El, the lower 4o end of which bears against said pin. The upperend of spring H supports a ball-valve, I, which closes the orifice J atthe upper end of the iiange, which orifice is, of course, round andground to form a seat for the ball-valve 45 I. The inner opening of thetube D, however,

is square, polygonal, or fluted, in order to per mit the lubricatingmaterial to pass by the valve.

The operation of our invention will be read- 5o ily. understood from theforegoing description, taken inconnection with the drawings heretoannexed. When the valve is forced in a downward direction the feed-tubemay he tilled with oil. When the pressure upon the valve is released thespring forces it upward, thus closing the feedopening, thuspreventingthe escape of lubricant, as well as the admission of dust anddirt.

Having thus described our invention, we claim and desire to secure byLetters Patent of the United Statesy In an axle-lubricator, thecombination, with the feed-tube having a square, polygonal, or flutedopening, and a transverse pin, ofthe spring H, the ball-valve I, and theholdingflange F, having an opening ground to form a sea-t for thesaidvalve, as herein described, for the purpose shown and specified.

In testimony that we claim the foregoing as our own we have heretoaffixed our signatures iu presence of two witnesses.
